• The computer to be monitored must be configured in the config.ini configuration file of the
TCU according to the general configuration for a TCU in a separate host section as a
switchover target for this TCU.
Where necessary, a password has to be specified in the configuration, if the VNC server
requires one on the target system (see below).
• To ensure that the TCU recognizes the new switchover target, the TCU requires a restart and
reboot.
• The screen resolution of the observed computer must be adjusted to the characteristics of
the TCU. Otherwise the TCU scales the image it receives to match the display area available
to the TCU, which impairs the quality of the display on the TCU.
